scp - secure copy

Scp copies files between hosts on a network. It uses ssh
for data transfer, and uses the same authentication and
provides the same security as ssh. Unlike rcp, ssh will
ask for passwords or passphrases if they are needed for
authentication.

Any file name may contain a host and user specification to
indicate that the file is to be copied to/from that host.
Copies between two remote hosts are permitted.
